Is possible to spawn entity and transfer it by transfer packet to another server? one people says that is possible
educated guess: no reason, only player is transferable entities otherwise will just have to stay here As for transferring specters... i still doubt it, but they seems to be able to do the handshake and so on
it is still consider a entity, you still cant do player only actions like $faked_player->sendMassage(""); etc that is restricted to Player instance ONLY
No, at least no normal entities. You can also not send a transfer packet to a specter, because it doesn't have support for that. Why not just send the entity data to another server and then let it spawn the entity.
